<P>PROBLEM TO BE SOLVED: To provide a method for producing composite particles of firmly sticking small organic particles on the surface of organic or inorganic mother particles by simple production processes without using an organic solvent harmful to a human body. <P>SOLUTION: This method for producing the composite particles of sticking the small organic particles on the surface of the organic mother particles is provided by mixing the small organic particles with the organic mother particles, then in the presence of carbon dioxide at a critical temperature or higher and under ≥4 MPa pressure, plasticizing the small organic particles in a container and then removing carbon dioxide. Also, the method for producing the composite particles of sticking the small organic particles on the surface of the inorganic mother particles is provided by mixing the small organic particles with the inorganic mother particles, then in the presence of carbon dioxide at the critical temperature or higher and under ≥4 MPa pressure, plasticizing the small organic particles in the container and then removing carbon dioxide. <P>COPYRIGHT: (C)2007,JPO&INPIT |
